Trouble with reading CSV file in R -

-

i'm newbie in r. have 24mb csv file. reads rstudio on macbook air os yoswmite, 4gb ram. r version 3.1.1 (2014-07-10). viewing contents of view (df) ok. attempting apply filter. not hits. attempting cast character number. r replacing charaters na in column casting done! happens here? seems r can not read contents of cells. there encoding? have done fare: first summary:

r code:

eiendommer <- read.csv("eiendommer.csv",  sep = ";", quote = "",  encoding="utf-8", stringsasfactors = false) view(eiendommer)# can view content of csv file filtereiendommer <- filter(eiendommer, kommune == "0101")# no match filtereiendom <- eiendommer [eiendommer$kommune == "0101",]#no match utvalg <- eiendommer[160567:161934,]#manual selection of rows work             utvalgsortert <- arrange(utvalg, desc(jordbruksareal), desc(skogareal))# works view(utvalgsortert) ##try transform columns character number.  transformedeiendom <- transform(sorterteiendom, jordbruksareal = as.numeric(jordbruksareal),                        skogareal = as.numeric(skogareal) ) #this result in na earlier characters lengt 1-3:"646", "18", "2"

it appear have specified quote = "", in fact should have, , perhaps quote='"' or default value work.

see example below

d <- data.frame(x='a',y='"a"',stringsasfactors=false) d  #   x   y # 1 "a"

for regular character vector, print.data.frame not enclose in "

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
